Philosophy of Everything

  Better read: Data Consistency in Distributed System - CAP, PACELC Morality series - a heptalogy This blog is mainly focused on my Philosophical and theoretical ideas. From time to time I have practical posts that are too few to deserve a blog by themselves. I still hope my other work (like above) is even more valuable than such practical article as below. * * *     Update 2022: Bose QC45 is almost the same as Bose QC35 II , however it has USB-C charging. Note that Bose QC 45 does not have NFC anymore - used for fast Bluetooth connection.   Updates 2020 :  Bose QC35 II (2) is basically identical as sound, look and feel to the original QC 35. The only adding is a button that can be used to activate Google Assistant or alternatively to change the noise cancelling level. Bose QC35 (1 or 2) remains the best noise cancelling headphones that I ever tried, especially because of the ear comfort and ergonomy, along with long battery life. Another big advantag...

"Noise cancellation " is a feature in recent high-end headphones that aims to actively remove the outside noise while listening music. You can also use them without music, however the efficiency is lower. "Noise cancellation" is a relatively new technology and you must be aware of what is reasonable to expect from such headphones. Noise cancellation - how it works

I am passionate about sound quality lately. Here are my early conclusions from the research and experiments I did. This is the order of sound optimizations that you could try in order to improve the music experience. 1. Live music sounds better than recorded music 2. Un-amplified live music sounds better than amplified music 3. Recorded music sounds better on loud speakers than on headphones 4. Expensive headphones (>100$) sounds better than cheap ones 5. Open-air headphones sounds better than closed enclosure ones 6. Loss-less music (like FLAC) sounds better than MP3 7. High bitrate MP3 (>128kbps) sounds better than low bitrate 8. A professional DAC (or sound card) sounds better than a cheap one 9. High sample rate music (>44KHz) could sound better than 44KHz (or not) 10. Music encoded at 24bits could sound better than 16bits music (or not)  I will say a few words about each, from my limited experience and research:
